Abstract: PURPOSE: To produce a hybrid circuit which can be used over the whole frequency by connecting two diodes so as to be opposed and applying the connection point to the 1st input terminal and the opening terminal of one diode to the 2nd input terminal.  
     CONSTITUTION: When detecting signal current i 0  flows, currents i 1 , i 2  flow into diodes D 1 , D 2  and the capacitance of these currents i 1 , i 2  is equal because the impedance of a transformer 2 is uniformed with that of a balance circuit 4. Therefore, current i 3  is turned to "0" and a transmission signal discriminating circuit 5 generates no output. At that time, sound is outputted from an acoustic transducer 3 in accordance with the current i 1 . When an input is supplied to the acoustic transducer 3, voltage is applied to the transformer 2 and then the current i 3  flows into the input resistance in the transmission signal discriminating circuit 5, so that the transmission signal discriminating circuit 5 generates an output.

Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic recording medium having excellent electromagnetic conversion characteristics and a low error rate near the tape edge by forming plural magnetic layers on a nonmagnetic base body having a specified shape. SOLUTION: A nonmagnetic base body 2 comprising a flexible film material is firmly stretched in the longitudinal direction to give tension. The ratio of the Young's modulus in the longitudinal direction to the Young's modulus in the width direction is specified to 1.5 to 3. Thus, edge damages are decreased and good contact between a tape and a head is obtd. Then a magnetic coating material containing a hexagonal oxide magnetic powder dispersed in a binder is applied to 0.05 to 0.5μm thickness on the base body 2 to form a first magnetic layer 3a. Then a magnetic coating material containing a ferromagnetic metal powder having 1300 to 2600 Oe or more coercive force essentially comprising iron is applied to 0.05 to 0.5μm thickness on the layer 3a to form a second magnetic layer 3b.  The difference in the coercive force between the first and second magnetic layers is controlled to 200 to 2000Oe. Thereby, the error rate in the tape edge can be decreased, and the electromagnetic conversion characteristics with good balance in a low range and a high range can be obtd. by forming the first and second magnetic layers.
